This list of Anuran families shows all extant families of Anura. Anura is an order of animals in the class Amphibia that includes frogs and toads. More than 5,000 species are described in the order. The living anurans are typically divided into three suborders: Archaeobatrachia, Mesobatrachia, and Neobatrachia. This classification is based on ...
Depending on the species, male or female toads may possess a Bidder's organ, a trait unique to all bufonids except genera Melanophryniscus and Truebella. [8] Under the right conditions, the organ becomes an active ovary. [9] The loss of teeth has arisen in frogs independently over 20 times. Notably, all members of Bufonidae are toothless.
The Anura include all modern frogs and any fossil species that fit within the anuran definition. The characteristics of anuran adults include: 9 or fewer presacral vertebrae, the presence of a urostyle formed of fused vertebrae, no tail, a long and forward-sloping ilium, shorter fore limbs than hind limbs, radius and ulna fused, tibia and ...
Hyloidea accounts for 54% of all living anuran species. [2] The superfamily Hyloidea branched off from its closest relative, the Australobatrachia , during the mid- Cretaceous . [ 3 ] The fossil evidence found during the Cretaceous-Paleogene extinction event could not determine the effects upon the frogs, due to the lack of fossils.
The Neobatrachia (Neo-Latin neo-("new") + batrachia ("frogs")) are a suborder of the Anura, the order of frogs and toads.. This suborder is the most advanced and apomorphic of the three anuran suborders alive today, hence its name, which literally means "new frogs" (from the hellenic words neo, meaning "new" and batrachia, meaning "frogs").
List of Anuran families Toad is a common name for certain frogs , especially of the family Bufonidae , that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands .
Hyla japonica, commonly known as the Japanese tree frog, is a species of anuran native to Japan, China, and Korea. H. japonica is unique in its ability to withstand extreme cold, with some individuals showing cold resistance at temperatures as low as −30 °C for up to 120 days. [2]
